Product Overview

The Automatic Cold Roll Forming Machine for AG Roof Panel is designed for agricultural building manufacturers, metal roofing roll formers, post-frame contractors, and pre-engineered steel construction suppliers. Agricultural AG panels (and C18 trapezoidal sheets) represent the global benchmark for cost-effective, high-durability roofing and exterior wall envelopes.

The machine handles standard 1250mm wide coils of prepainted galvanized steel (PPGI), galvalume (PPGL), and galvanized sheet (GI) across thicknesses from 0.4mm to 0.8mm. The formed panel delivers 1048mm (or 36" 914mm) effective coverage with integrated anti-siphon capillary ribs for complete structural weatherproofing.

AG Roof Panel Roll Forming Machine Overview & CAD Profile

Key Technical Features

• Hard Chrome Plated Forming Rollers: Precision CNC turned from 45# forged structural steel, vacuum quenched and electroplated with 0.05mm hard chrome to eliminate coil scuffing and preserve paint finish.
• Integrated Anti-Siphon Weather Barrier: Overlap rib stations form an engineered capillary anti-siphon groove, preventing water ingress under severe storm conditions.
• Heavy 400mm H-Beam Machine Chassis: Stress-relieved heavy structural H-beam foundation guarantees rigid roller station alignment across high-tonnage rolling cycles.
• Cr12MoV Guided Hydraulic Cut-Off: High-tonnage hydraulic shearing station equipped with Cr12MoV vacuum heat-treated blades ensures smooth, burr-free cuts.
• Synchronized Chain Transmission: High-tensile double-row drive chains deliver steady rotational torque to upper and lower roller shafts without slippage.

Multi-Stage Precision Forming Stands

The roll forming machine features gradual bending stations precision-spaced along the 400mm H-beam foundation. Sequential roller passes gently bend the high trapezoidal ribs without material thinning, while maintaining strict rib pitch tolerance.

• Gradual Forming Progression: Multi-pass stations gently contour the ribs, eliminating internal stress and panel camber.
• Heavy Chain & Sprocket Drive: Double-row heavy roller chains provide synchronized rotation of upper and lower roller shafts.
• High-Strength Tie Rods & Bearings: Heavy-duty self-aligning bearing blocks withstand continuous rolling loads without alignment drift.

AG Roof Panel Profile Geometry & Engineering Blueprint

The AG Panel profile complies with international building and agricultural cladding specifications:

• Effective Cover Width: 1048 mm (or 36" 914 mm) effective coverage
• Major Rib Pitch & Height: Standard agricultural rib spacing with 19mm rib height for structural stiffness
• Intermediate Stiffening Ribs: Dual minor V-ribs between major ribs to prevent oil-canning and boost panel rigidity
• Siphon Barrier: Anti-siphon groove along overlap flange for 100% weather tightness

Broad Agricultural & Industrial Applications

AG panels and trapezoidal metal sheets are the most widely installed building envelopes worldwide:

• Agricultural Buildings & Barns: Highly popular for equestrian barns, grain storage sheds, and livestock facilities.
• Commercial Warehouses & Steel Workshops: Fast screw-down installation with high wind resistance for industrial facilities.
• Residential Carports & Roof Retrofits: Lightweight, economical metal roofing over existing shingles or open timber framing.

Supply Scope & Ocean Shipping

Turnkey supply scope includes 5-ton manual decoiler (hydraulic decoiler optional), automatic roll forming main machine on 400mm H-beam frame with protective covers, Cr12MoV hydraulic profile cut-off station, standalone hydraulic pump station, Siemens PLC touchscreen console, and finished panel runout tables.

All precision chrome rollers and shafts are coated with anti-corrosion protective grease. The entire machine chassis is securely anchored inside a 40ft HQ shipping container using steel wire cables and timber chocks. The electrical control console and hydraulic station are hermetically wrapped in waterproof film and crated in export plywood cases.
